soon-to-be

The compound adjective "soon-to-be" is a modern English formation built entirely from native Germanic elements. Its logic is transparent and syntactic, directly mirroring the common adverbial phrase "soon to be." The word "soon" originates from the Old English concept of immediacy. Combined with the infinitive "to be," it creates a future-oriented descriptor. This grammaticalized phrase was lexicalized in the 20th century to efficiently pre-modify nouns, succinctly indicating an imminent change of state or acquisition of a new identity, such as a "soon-to-be graduate" or "soon-to-be mother."
